[SYCL][E2E][TEST] Unplug sycl_device_globals on NVIDIA RTX 3090 (#21867)

Temporarily disable sycl_device_globals on NVIDIA RTX 3090

The test is expected to work on this device, but is currently
experiencing a high rate of intermittent failures
(#20408). To avoid blocking
contributors whose changes are unrelated to this issue, execution is
being turned off on RTX 3090 until the root cause is identified and
fixed.

Additionally, occurrences of "\n" in print statements have been replaced
with std::endl to ensure output is flushed immediately and remains
visible in test logs in the future.
